This project is to be done with one partner. Teams have been assigned on the wiki page. You will be presenting your project information on the wiki itself. You will be creating the page, importing images as well as other information that will be pertinent to the project. Please read the directions carefully and answer each question to the best of your ability. Also please be sure to show all calculations.
Part 1:Begin by doing the following problem. It will help you in doing the larger problem that follows. Please do the graph on a sheet of graph paper and write all your answers on the graph paper. This problem is worth 40 points. Jack plants a bean. Seven days later it has sprouted and is 10 feet tall. On the 8th through the 15th days its heights are 17,20,25,32,36,38, and 44 feet, respectively. Let x be the number of days since the bean was planted and let y be the number of feet tall. a. Plot the graphs of the given ordered pairs. 10 pts b. Describe the type of correlation seen in the set. Be specific in your description. 5 pts c. Find the average of the x coordinates and the average of the y coordinates, this is your “anchor” point; then plot it. 5 pts d. Draw the straight line through the anchor point that seems to “fit” the points the best. This is called the “line of best fit.” 4 pts Take a picture of this and post it on your project wiki. Be sure to label the picture correctly. All of the answers to each of the following should be posted on the project wiki as part of part one. Be sure to hand in work as well on loose leaf.
From the graph, use the anchor point and one other point on the line to find the slope and the equation for the line in slope-intercept form. This is a graphical prediction of the height in relation to time. 6 pts
Using your answer to part e, answer the following questions. f. Approximately when did the beanstalk emerge from the ground? 5 pts g. Approximately when will the beanstalk be 100 ft tall? 5pts
The Hurricane Problem ~ 160 points
Go to http://www.nhc.noaa.gov/pastall.shtml and collect data from 5 different hurricanes. To do this look under “Tropical Cyclone Reports” and choose a year under the “Atlantic, Caribbean, and Gulf of Mexico” section. When you choose a hurricane open the pdf file. The data is a few pages into the file. You will have to hand type the data into a separate Google spread sheet for each hurricane. Work with your partner to accomplish this. You must have one hurricane that reaches category 5 in the Saffir-Simpson Scale. Do not use the data under the column “speed”. (Please omit any coordinate with a ?? as a value). Use this data to plot the graph of wind speed versus air pressure using graph paper. Therefore you will have 5 tables & 5 graphs! [50 points (10 points for each hurricane)] All 5 graphs and tables should be posted on the wiki. The google spreadsheet can be imbedded into the wiki. You can post a photo of your graph as well.
For EACH of the 5 hurricanes, do the following steps: This work should be posted on the wiki, as well.(complete each hurricane on a separate piece of graph paper)
Describe the type of correlation seen in the set. Be specific in your description. [10 points (2 points each)]
Find the average of the x coordinates and the average of the y coordinates, this is your “anchor” point; then plot it. [15 points (3 points each)] *You can use your graphing calculator to find the averages (1-VarStat) OR use the formula = sum( ) in Excel, ex:=sum(a2:e2)/5.
Draw the straight line through the anchor point that seems to “fit” the points the best. [5 points (1 point ea)]
From the graph, use the anchor point and one other point on the line to find the slope and the equation for the line in slope-intercept form (standard form of a line: y=mx+b). [25 points (5 points each)]
How different was the equation for each hurricane? [10 points (2 points each)]
What is the average slope and speed-intercept for all 5 hurricanes? Write a new equation using these values using appropriate variables. [2 points, 2 points, 2 points]
All of the following should be answered on the wiki. 7. Using the equation from 2f, predict the wind speed for pressures of 1000 mb, 900 mb, 1020 mb, and 1015 mb. [4 points (1 point each)]
8. Describe in detail the relationship between wind speed and air pressure. Type in MS Word. [4 points]
9. Research the Saffir-Simpson scale for hurricane classification. Type in MS Word. a. Describe the scale in detail and in your own words. Do not just copy and paste from the Internet. [4 points] b. On the y-axis of your wind speed versus pressure graphs, indicate at which wind speed each category would cover. [3 points] c. State which of your five hurricanes fell into each level of the scale. [4 points]
10. Research a recent hurricane. In paragraph form (using MS Word), be sure to discuss where it developed, where it made land-fall, the cost in human lives, and the estimated economic cost for the region it hit (example: recovery/rebuilding costs). Be sure to state the category of the storm as well as to discuss the history of the storm. [20 points]
Finally, The wiki should be well organized and easy to follow. Feel free to add pictures, etc. to make it more appealing. [10 points]
